Series fpca pwc1/pwc2 power supplys

GENERAL INFORMATION
Dwyer Instruments Inc. offers a selection of power supplies 
for use in a variety of applications. The appropriate power 
supply is chosen based on the power requirements of the 
specific component(s) in the application as well as the desired 
mounting style.
The PWC1 is a single 24 Vdc unregulated power supply that 
plugs into a 120 Vac outlet. Since it is unregulated, voltages 
can vary up to approximately 32 Vdc depending on the load. 
The PWC1 should be used only in applications where these 
voltages are tolerated.
The PWC2 is a regulated dual power supply (12 Vdc and 24 
Vdc) for use in applications where a magmeter is used along 
with a 4-20 mA transmitter. Though a single power supply can 
work in such applications, the PWC2 eliminates the risk of 
potential ground loop interference. The PWC2 is designed for 
wall or panel mounting.
